IE9 Ignoring Style Sheet

Kei

IE9 seems to be ignoring the style sheets from RadStyleSheet for a custom skin if it is not running in compatibility mode. I have a custom skin from the Visual Style Builder that I made into an assembly and added as a DLL to my website. I tested it on a sample page and this is the error that IE gives me:
